This invention relates to an auxiliary window of the type in which panes of glass provide closure means supplemental to the standard window, and in which the panes are interchangeable with screens.

An object of the invention is to provide an auxiliary window of the type described adapted to be installed interiorly of the standard window, the same having improved means whereby glass and screen closure panels may be quickly and interchangeably mounted from the interior, in accordance with weather changes, and without creating a problem oi storage of closure panels not necessarily required at a particular time.

Other objects of the invention will be manifest from the following brief description and the acbroken away, taken substantially on line 4-4 of Figure 1.

Figure 5 is an enlarged fragmentary cross-section, taken on line 5--5 of Figure 1.

Figure 6 is a fragmentary cross-section, corresponding to the lower portion of Figure 3, and illustrating a inodied form of the invention.

Referring to Figures 1 to 5 of the drawings, the

numeral I D designates a window frame of standard type having trimming strips II, II inwardly of the usual double-sashed window (indicated in chain-dotted lines in Figure 2), which strips for the present purposes are utilized as a blind stop providing an interiorly presented blind seat I2. Hinged to one side oi frame I0, as indicated at i3, I3, may be top and bottom sashes I4 and I5, respectively, of an auxiliary window adapted to be seated snugly within frame I0 against the blind seat i2, the sashes being swingable interiorly on the hinges I3.

The top sash ill comprises Stiles I6 and I'I, top and bottom rails I8 and I9, and an intermediate rail 25, defining vertically spaced openings 2I and 22. Similarly, on bottom sash I5, stiles 23 and 24, and rails 25, 26, and 2l, dene openings 28 and 29. The adjacent rails I9 and 25 of the top and bottom sashes may be complementally ofi-set, substantially as best shown in Figure 2, to provide an effective seal against cold air and dirt from the exterior. Suitable catches 3,8 are provided on the inner face of frame I!! for retaining the sashes in closed position.

rlhe inner opening edges of the stiles and rails may be slotted as indicated by the numerals 3|, 32, 33 and 32 for slidably removably receiving closure panels comprising either a glass pane 35 or a screen 55a, the guide slots in the stiles I6 and` 23, at the free side of the auxiliary window being extended through said stiles to facilitate insertion and removal of the panes or screens whiley the sash or sashes are in outwardly swung position (see Figure 4). These guide slots may4 be wide enough to receive either one or two closure panels in superposed relation, and in either case spring clips 35 secured to the stiles may have arms 36a suitably shaped to extend inwardly ofv the slots, with a minimum portion of the clips exposed in the closure openings, yieldingly tol urge the closure panel or panels toward one side relatively of the plane thereof, against the inner portions of the slots. sure panels against rattling.

Guide strips 31, 3l may be secured to extend i'n parallelism along the top and bottom edges of each closure opening, these strips having oppo' sitely inturned flanges 31a for retaining either glass panes 35 or screens 35a against the outer face of the auxiliary window. The guide strips 3l are open at the end adjacent the free side of' the window to permit insertion or removal or" the' panes or screens while the window is in open posi-f tion.

In the use of the auxiliary window in the, win: ter season, for example, it is normally maintained in the closed position, best shown in Figures l, 2 and 4, with a single glass pane 35 retained in each closure opening 2i, 22, 28 and 29, for effective insulation against cold air, and with a screen 35a retained over the top and bottom openings 2l and 28 by guide strips 3l. Screens may be retained over the other two openings if desired. Should fresh air be required at any time, either the lower sash I5 may lbe left partly open, in the relative position shown in Figure 4, or the top or bottom panes 35, or both of the same, may be 'removed and inserted between the guide strips-3l of openings 22 and 28. If there are screens retained over the last-named openings the panes may be inserted in the slots 32 in superposed relation to the panes already received therein, in the manner previously described. During the warmer seasons of the year the auxiliary window may be normally maintained with the openings screened as described above for Ventilating purposes. It is possible, however, with equipment as shown, to have as many as three closure openings open except for screens, as by storing two glass panes in the slotted portions of one of the openings and storing a third pane between the guide strips 3l of the same opening. Thus various combinations of glass or screen coveredopenings may be accomplished without the usual prob- The clips 3E retain the clolem of what to do with closure panes or screens not necessarily required at a particular' time.

In Figure 6 is shown a modified form of the invention, in which spaced slotted portions d and 4i are provided, in place of the above described single-slotted portions, for receiving glass panes or screens in various combinations, the operation and use thereof being otherwise similar.

Modications of the invention maybe resorted to Without departing from the .spirit thereof or the scope of the appended claims.

What is claimed is:

1. The combination with a window frame having an inwardly presented blind seat, of an auxiliary window received in said blind seat and hinged Vat -one side to said window frame, said window having stiles and vertically spaced rails, said stiles and said rails being slotted around the inner edges thereof for receiving a closure panel in closed position thereof, the slot of the stile at the free side of the window being extended through the stile, a closure panel received in said slots and being insertable and removable through said extended slot at said free side of the window, and yielding means in said auxiliary window for yieldingly engaging said closure panel at one side relatively of the plane thereof to urge the same toward the opposite side of the slots therefor, said pressure members including guide portions being in the path of and thereby yieldingly engageable with the leading edge of said closure panel as the same is inserted through said extended slot and moved toward said closed position within said inner edge slots,

2. yThe combination with a window fra-me having an inwardly presented blind seat, of an auxiliary window received in said blind seat and hinged at one side to said window frame, said window having stiles and vertically spaced rails to provide a plurality 'of window openings, said Stiles and Vsaid rails being slotted around the inner edges thereof in said openings for receiving closure panels in closed positions thereof, the slots of the stile at the free side of the window being extended through the stile, closure panels received in said slots and being insertable and removable through said extended slots at said free side of the window and a plurality of resilient pressure members in said auxiliary window in cooperation with each window opening thereof for yieldingly engaging said closure panel at one side relatively of the plane thereof to urge the same toward the opposite side of the slots of the respective window opening, said pressure members of the respective window openings including guide portions adapted to be in the path of and thereby yieldingly engageable by the leading edge of the closure panel as the same is inserted through said extended slot.
